WATER-=PROOF STRUCTURE IN BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 389,914, datedSeptember 25, 1888.

Application filed October 17, 1887. Serial No. 252,56

To all whom it may concern:

Be it known that I, FRANK T. WHALEN, of New York, in the county andState of New York, have invented a certain new and useful Improvement inlVatenProof Structures in Buildings, of which the following is aspecification.

My improvement relates to houses and other buildings. I

The object of my improvement is to afford an effective protectionagainst watcrand moisture.

The improvement may be used in a cellar-lining, in foumlation-walls, orin a roof, vault, cover, or sidewalk.

In the accompanying drawings, Figure 1 is a Vertical section of apart ofone of the foundation-walls of a building and of a portion of a cellarin such building. Fig. 2 is a plan or top View of the ccllar-floor in anincomplete state.

Similar letters of reference designate corre sponding parts in bothfigures.

A designates a surface upon which the flooring of the cellar is laid.-This surface A may be the earth smoothed off, or it may be made ofruddle or of any other suitable material. The surface A will be leveledand will also be smoothed off as much as practicable. Upon the surface Aare laid a number of layers, 13 C, of roofing-paper and roofingeement.The layers of roofing-paper androofing-cement will preferably bealternated, or, in other words, a layer of the roofingcementwill beplaced between each two layers of the roofing-paper. The roofing-papermay be of ordinary kind, consisting of a heavy paper saturated orimpregnated with tar, pitch, asphaltum, or like substance. Theroofingcement, of which layers are interposed between the layers ofroofing-paper, may be of the same substance as that incorporated intothe roofing-paper.

D designates an upright wall of masonry forming one side of the cellar.It maybe faced with mortar or concrete, E, so as to have a smooth innersurface. Layers B O of roofingpaper and roofing-cement, arranged likethose heretofore described as laid upon the surface (No model.)

A, may be laid against the surface E, and these upright layers of theroofing-paper will overlap the horizontal layers of roofing-paper.

G designates a course of bricks,which are thoroughly saturated orimpregnated with tar, pitch, or asphaltum. Preferably they will beimmersed in the tar, pitch, or asphaltum while the latter is boiling andallowed to remain sufficiently long for the air, or at least a portionof the air, in their interstices to be expelled and for the tar, pitch,or asphaltum to enter the interstices or pores. These bricks will beimpervious to water; hence they are capable of preservation almostindefinitely, for if the water be excluded from them danger from frostwill be obviated. Of course I do not wish to be restricted to a singlecourse of these bricks. Between the bricks are layers 9 of the tar,pitch, or asphaltum. Preferably the tar, pitch,or asphaltum will extendentirely around the bricks.

The bricks may form theflooring, or there may be laid over them a courseof Portland cement or other like substance capable of being made veryflat and smooth. Sand may be mixed with the tar, pitch, or asphaltum onthe top to make a rough surface, which will cause the Portland cement orlike substance to adhere. These bricks may be laid in the foundationwalls of the building where the latter are exposed to moisture. They mayalso be used upon roofs.

What I claim as my invention, and desire to secure by Letters Patent, is

A building havingin a portion of its structure which is exposed to wateror moisture a course or a number of courses of bricks saturated orimpregnated with tar, pitch,'or asphaltum, each of the bricks beingentirely surrounded with tar, pitch, or asphaltum, and alternate layersof roofing-paper and roofingcement adjacent to the courses of thebricks, substantially as specified.
